' neatb the table, as well as Iby the foot applied to the Be it known that Loom,v Oceanus, Jr., of tiva-Heimr- Malden, in the county ot' Middlesex amtStatc ot' assacbnsetts, have invented an .Improvement in ewing-machine Driving Mechanism; and I do lieve-- and table with a t-readle and treadle-shatt and scwing-macbine shaft embodying my improvement.

A denotes a side elevation, and

a sectional elevation ot' the mechanism. a denotes the-sewing-machinetrame, the work-supporting,r plate b of winch rests drectlyonthe table o, the shaft d being belted by a band, e, to a shaft,j; -or to a fly-wheel, y, upon said shaft.

thedlawing which accompanies and forms part of this specification, is a description ot' in y invention sui'- Although sewing-machines are sometimes made to be run by band, almost allltinds of sewingmachines are mounted upon tables and have their tliivingslialts actuated by treadle, or footdriven shafts placed b'ethe sewing-machine mechanism being belted to the treadle-driven shaft, the work-supporting;r plate ofthe sewing-machine generallyresting directly on the table Sometimes, however, an ordinary band-driven machine is mounted upon a table and belted to the crankshaft beneath the table, 'so that the machine may be either driven by band, (applied to the clank-handle extending ti'om the sbatt above the table,) or by the foot applied to the .treadle beneath.

t is well known that it is very tiresome to many weinen, and injurious tomany, to dn've sewing-ma? chine treadles, but, where a achine that can be driven by .band is mounted `upon a table, and connected with a treadle mechanism beneath the table, it is immachine may still be run without obstructing the fi'ee nlovement of the work, by applying the hand above the table. 2 I
